Question

我有一个从缓冲区获取数据的函数，并将它们转换为字符串，如您所见：

public string GetParameters(byte[] buf)
{
    string result = System.Text.UnicodeEncoding.Unicode.GetString(buf);
    return result;
}

另一个应用程序将一个Farsi字符串发送到缓冲区，我的应用程序应该获取此数据，但我的应用程序的函数返回：

为什么？

我如何接收缓冲区数据：我定义了这个：

public byte[] dataBuffer = new byte[4000];

我有这个功能：

 public void WaitForData(System.Net.Sockets.Socket soc)
        {
            try
            {
                if (pfnWorkerCallBack == null)
                {
                    // Specify the call back function which is to be 
                    // invoked when there is any write activity by the 
                    // connected client
                    pfnWorkerCallBack = new AsyncCallback(OnDataReceived);
                }
                SocketPacket theSocPkt = new SocketPacket();
                theSocPkt.m_currentSocket = soc;
                // Start receiving any data written by the connected client
                // asynchronously
                soc.BeginReceive(theSocPkt.dataBuffer, 0,
                                   theSocPkt.dataBuffer.Length,
                                   SocketFlags.None,
                                   pfnWorkerCallBack,
                                   theSocPkt);
            }
            catch (Exception qqq)
            {

            }

        }

还有一个：

 public void OnDataReceived(IAsyncResult asyn)
        {
            try
            {
                SocketPacket socketData = (SocketPacket)asyn.AsyncState;

                int iRx = 0;
                // Complete the BeginReceive() asynchronous call by EndReceive() method
                // which will return the number of characters written to the stream 
                // by the client
                iRx = socketData.m_currentSocket.EndReceive(asyn);
                string res = GetParameters(socketData.dataBuffer);
}

Answer 1

尝试使用UTF-8：

string result = System.Text.UnicodeEncoding.UTF8.GetString(buf);

对我来说，看起来像波斯语。（但我不会说波斯语。）

这里提到了Unicode和UTF-8之间的区别：UTF-8 vs. Unicode

基本上，角色的长度会有所不同。

Answer 2

string myDecodedString = Encoding.GetEncoding("1256").GetString(buf)

在c＃中获取unicode缓冲区字节返回'??????'
